Granit Xhaka has revealed that his goal celebration for Arsenal was conjured up in a dream.

The midfielder scored stunning long-range strikes against Hull City and Nottingham Forest, and many had linked his celebration with speculation surrounding his international future as he now has the option to play for Kosovo.

But the £35 million summer signing insists his gesture was made on the spot.

‘It was spontaneous and I didn’t plan it,’ he told Arsenal’s official website.
